EKO Duo 300 Boiler

So far I have been happy with the MBTEK Duo 300 Boiler. It took a long time to get the unit, but it seems to be very well built. This is a very large Boiler, We have 4 buildings that this unit is heating. It has kept everything warm through the recent Blizzard and cold spell, so I am pleased with the output. We are still trying to get the settings right so that we are not using too much fuel, but that will come with time. The biggest complaint I have is that the unit only reads in Celsius, and cannot convert to Fahrenheit. Also the unit runs on 230v so has to have a power converter.
